Hi there,

I have a ‘91 CQ and noticed today that AC blower does not shut off with the AC unit. The delco unit seems to work fine otherwise except that OFF/LO/HI have no effect on the blower speed which is stuck on high. 

The only way to shut off blower is to turn the ignition off. 

Any thoughts?
